Less felt recoil. Softer recoil.What are the perceived advantages of the A5 system?

With the different lengths and profiles of large frame bolt carriers there is not a lot of easy mix and match here, stick with the profiles the OEM shipped it with.
This is a major pain point for franken-gun AR10 builds as there are so many conflicting standards.

I don't want a oil filled tube In my gun with proprietary apartsThen JP SCS which does fit LFAR platforms. Pair with a JP LoMass BCG and tune the gas along with the adjustable buffer weights and springs to get the lowest reciprocating weight that will still run the gun reliably. It's not a complicated process and results in the lowest recoil/ shortest recoil cycle I've felt on a 308W gas gun.

Have you shot that set-up both in the extreme cold and summer?I've found the Tubbs flat wire spring combined with a Kynshot hydraulic buffer provides a very soft recoil impulse. This is in an A5 length receiver extension tube. I don't recall which model buffer I used. I've used the hydraulic buffer for 2500+ rounds without any issues.
I've not used it in extreme cold. I'd say it's been run between 40 and 90F. It's in a gas gun I use for prs.Have you shot that set-up both in the extreme cold and summer?
One of the challenges with hydraulic fluid cylinders and temperature gradients is loss of the seals from cycles in varying temp and pressure environments. They work amazingly-well with such a smooth feel to the action, until they fail.
2500rds is a good run though. I hope it continues to work for you for another 2500rds.
They have always interested me.

Th heat is great for seals as long as you stay within a pretty narrow temperature range (flatland AZ).i have an original endine hydraulic buffer and have not seen any issues regarding temps hot or cold but i live in s. az. its been shot plenty in the heat.
That is so funny because Stoner originally wanted to build AR-10s for the Army back in the day but they went with KAC in spite of problems.You will not be using an A5 buffer with a large frame DPMS in an A5/ArmaLite RET, but the A5 RET is what you want.
The ArmaLite/A5 RET is great for the large frame carbines because you can use a longer AR-10 spring and the common AR-15 carbine length buffers, vs the tiny little DPMS LR-308 carbine buffers that kinda suck.
The biggest problem with using a standard AR-15 carbine RET with a large frame AR is that they don’t allow enough spring length to fit in there. The A5 RET allows a full-length extra power AR-10 rifle spring, so when you pair that with an AR-15 carbine buffer, the guns run like they’re supposed to.
ArmaLite Inc. was probably the first company to crack the code of reliability with an AR-10 carbine in the 2000s. KAC had a lot of problems with the early SR-25K and MLGS 16” SR-25s using standard AR-15 carbine RETs. They went to mid-length RETs and longer action springs quite some time ago.
